agens-graph - 如何在 AgensGraph 上删除“GRAPH”？

Question

我试图删除图表。删除图表时发生错误。

# drop graph graph;
ERROR:  cannot drop graph graph because other objects depend on it
DETAIL:  sequence graph.ag_label_seq depends on schema graph
label ag_vertex depends on schema graph
label ag_edge depends on schema graph
HINT:  Use DROP ... CASCADE to drop the dependent objects too.

如何删除“图形”？

Answer 1

删除图形时，必须先删除所有数据和架构。

为方便起见，可以使用可选的“CASCADE”子句。

# drop graph graph cascade;
NOTICE:  drop cascades to 3 other objects
DETAIL:  drop cascades to sequence graph.ag_label_seq
drop cascades to label ag_vertex
drop cascades to label ag_edge
DROP GRAPH
